...are you at the correct location? Sorry but had to ask. If you are, is the weather crappy (that sometimes affects whether you can take a photo or not). You don't state whether you have stock SH4 or one of the super mods (i.e. TMO). There should be a 'camera' button (button with the image of a camera on it) along the bottom of your screen which, when you are in the right position, will light up, simply click on it.
